I wasn't sure about bumping old topics, so I thought it would be better to make a new one, btw.
Anyway, my problem is this: whenever I go to a sim, there is no issue at all. I have full connectivity, almost zero lag, et cetera. However, after anywhere between 1 and 10 minutes after loading the sim initially, the connection drops to zero. I can't load the search function, update information, or anything.
Now that might not be so bizarre, just a dud connection.. except it's not gone. I can teleport. And, once I teleport, the connection comes back full strength, for another period of 1-10 minutes, before it disappears again!
Now, for the sake of the problem I'll admit -- I used to use SecondLife about a year or two ago, on this very computer, same network configuration and all - no problems. Now there is a major problem! I use an Asus laptop with 2gb of RAM and over 100gb of free space still. I have a 100Mbps wired connection behind a router - all the non-laptop computers in my house haven't got an issue at all - and deactivated all firewalls (the router's and my own), in case they were the source of the problem. My CPU is an Intel Pentium III.
Still, the connection dies every time.
It's truly bizarre, and I don't know what to do? Is it something obscure I've overlooked? Something obvious? Is it my SL version (1.23.5)?
Another member of my family has an identical laptop to mine (it was a popular laptop with us hehe

So, er.. help? This is extremely frustrating
